` To all 'whom t may concern.'

Be it known that I, PlanarA EDWARD HAUGH, a citizen of the United States', reL siding at Millvale, in the county of Allegheny and4 State of Pennsylvania, have invented new and useful Improvements in Shock-Absorbers, of which the following is a specification.

- an effective manner which will prevent 'the breaking of the springs of an automobile or other vehicle 'and also relieve-the thrust and disagreeable and quick inovementssimparted to the body of the vehicleand the 'occupants of the same.

The shock absorbing device is so connary automobile now in use.

lWith the above 'and other objects in view, the invention consists in the construction, combination and arrangement of parts, set

5 structed that it may be applied to any ordiforth in and falling within the scope of the appended claim. In thedrawingm-Figure 1 is a side elevation of the rear portion of anoautomobile, showing the axle in section, with the im, proved shock absorbing device applied thereto. Fig. 2 is a plan view of the saine, partly in section. Fig. 3 is a detail perspective view of the main spring member of the shock absorbingpdevice. Fig. 4 is a cross section on the line 5l-4l of Fig. l. Fig. 5 is a cross section on the line 5-5 of Fig. 1. Fig. 6 is adetail perspective view of the other member of the shock absorbing device.

The invention has been shown appliedto the ordinary automobile spring interposed between t-he body of the vehicle indicated at l and the rear axle 2, 3 designating the rear driving wheels of the machine. It is the ordinary practice to mount a semi-ellip tical spring l onthe axle 2, said spring heing retained in position by one or more clips The forward end of the elliptical spring 4 has a jointedconnection at G with the bodv and at its opposite or rear end it is connected by swing links 7 to the rear downwardly turned extremity of a Cshaped spring 8 which is rigidly 'securedto the body at 9. The construction t-hus far described is the ordinary spring arrangement.

In carrying out the present invention, I employ a shock absorbing single leaf spring 10, the central part of which is in the form of an inverted bow 11 which rests upon the top of the semi-elliptical spring 4 and is secured by the same 'clips 5 above referred to. the opposite end portions of the spring 10 are reversely bowed or curved as shown at A12 and the extremities thereof are bent around to form sleeves or eyes 13 which receive bolts 14 or their equivalent passing through U-shaped clips or yokes 15 and 16 embracing, respectively, the forward and rear portions of the semi-elliptical spring f1, as shown in Fig. 1. The end portions 12 of the shock absorbing spring exert a downward pressure and resist the upward thrust 'of the corresponding end Aportions of thel semnelliptical spring fl, thus relieving thei powerful upward thrust of the body after the wheels 'strike a sudden depression or eievation in the road.

In conjunction with 'the shock absorbing spring just hereinabove described, I also prefer to employ an auxiliary or complemental shock absorbing spring 17 having one end rigidly secured to the body preferably un'der the rigidly attached end of the C? shaped spring 8, as shown in Fig. l. The spring 17 extends forward and curves downward until near the extremity thereof where it is given a reverse bend to provide a lip 18 which rests upon the forward end of the spring 1'0, shown in Fig. 1. This complemental or auxiliary shock absorbing spring assists the spring 10 inresisting the upward movement of the body and spring of the vehicle and adds further to thev comfort of the occupants of the vehicle and also decreases the liability of breakage of the springs.
